Supporting production output of shortening of up to 20,000 kg/h, the scraped surface heat exchanger GS Nexus offers a number of unique benefits:

Low-energy production of crystallized fat products as mentioned below

Test results shows that using CO2 at -10°C gives approximately 25% less energy consumption in the refrigeration system, due to better actual efficiency on the compressor system at 10°C higher evaporation temperature than for NH3 operation.

CO2 is a very efficient refrigerant which has an external heat transfer coefficient which is 2-3 times higher than that of NH3 and which will increase the total heat flux by up to 40%.

Heat recovery system possible.

When using CO2 as regrigerant, it is possible to install and use heat recovery systems to save energy. The heat recovery can offer useable water up to 90°C, which can be used for other purposes in the pant. Up to 70% of the energy can be recovered.
